Research led by Queen’s University Belfast has shown that invasive species, such as the grey squirrel, European rabbit and Japanese knotweed, have cost the UK economy over £5 billion over the past 40-50 years. This is one of the highest totals in Europe. Invasive species, those introduced and spreading outside of their native range as a result of human activities, are a growing threat to environments worldwide. Environmental impacts of invasive species, one of the main causes of biodiversity loss, are well-studied. However, few studies have summarised their economic impacts. This study is the largest and most up-to-date combination of economic costs of biological invasions in the UK. The results have been published in the journal NeoBiota.

The Pacific Islands Marine Bioinvasions Alert Network (PacMAN) Project, which aims to monitor and identify marine biological invasive alien species, was officially inaugurated on November 24 in collaboration with the Institute of Applied Sciences at The University of the South Pacific (USP-IAS).
USP-IAS Acting Director, Dr Isoa Korovulavula stated it was a significant occasion as they moved collaboratively to a new "frontier" of protecting the local marine environment from invasive species. "The PacMAN Project is expected to boost local capability for early identification and warning of maritime invasive alien species. We are using revolutionary technology, such as DNA metabarcoding, to identify and deal with marine invasive alien species in our local marine environment," he explained.
